Comment 27 for bug 540332

nope, this happens also for the PHP and JAVA flavours of Eclipse.
besides that, changing the theme to something other than Ambiance or Radiance solves the problem.

So, is it a bad theme-ing decision to use dark backgrounds,
or the eclispe folks, who have not considered that the backgroundcolor may be dark, and forgot to set the foreground color explicitely?

Anyway, it is not user friendly, to tell folks to use a different theme, when their most used application is barely usable.

The problem with manually changing the colors is: eclipse may work, but you break tooltips in other apps!
For me, eclipse showed TTs with black text on light background, whereas Firefox tried to render background and text of Tooltips in light colors - same as above but the other way around. Only reason was to switch to a different theme.
